High resolution and high performance from opening of the diaphragm were also introduced as "starlit lens"
High-performance lens in which the point source at the periphery appears as a point
In other words, it is expected to be a fabulous lens with extremely reduced aberrations
I hear a story that considering the installation of "dew condensation prevention heater" to support it

"Starlit" I think I understand, but "things with things?"Perfect, a rear window defroster for my lens( or in Ford Motor Company parlance, electrically heated backlight). Will the metal conducting lines be visible in photos?

Ooku - I read this two, but I could not understand whether "starlit" is referring to:

A) The fact that it is part of the DA star series, and the high quality that implies
B) The suitability of the lens for taking images of stars
A&B) The writer is doing a kind of word-play on both of the above

I think you are probably right, and they are positioning this lens as the ideal companion for Astrotracer.

In the light of Yaotomi’s comment, it would be very interesting if the mystery switch on the lens turned out to be an on/off switch for an integrated heating element to prevent condensation on the lens.

Right, would make sense to relate to astrophotography, with high corrections. I guess the used phrasing is too explicit as to have been just a strange translation of "stellar".
However, I'm really looking forward to this lens, well corrected wideangle would have been the only pull factor for me to look at FF, but this could be now the perfect company with my KP.

The weight will be a result of the number of glass elements and metal components (i.e. "build quality"). The length will be largely dictated by the optical formula.

Those who have a genuine use for this lens won't be concerned about the weight or length

I have a use for this lens and I am concerned about length, weight and filter diameter. The 85 will be even bigger that is my major concern.
Do we have any clear information about dimensions yet? It looks big.
